To all whom t may concern.' I

Be it known that we, FREDERICK C. OVER- BURY and HOWARD CARLETON PLA'r'rs, of

New York, in the county of New York and State of New York, and of Rutherford, in

the county of Bergen .and State of New Jersey, respectively, have mvented certain new and useful Tmprovementsin Tile Roofings, of which the following 1s a speclca-4 tion.

This invention has relation to roofs or roof coverings, and has for its object to provide interlocking tiles formed of iiexible non-metallic weatherproof material.

The tiles are made of a flexible non-metallic weatherproof and waterproof material. Such'material consists preferably of a sheet of wool felt or its equivalent, saturated or impregnated with a waterproofing composition such as a suitable hydrocarbon, and coated on one or both sides with a layer or facing ofweatherproofng composition, such, for. example, as an -asphaltum paint, or a pitch or bitumen having arelatively high melting point, so that it will not be aected by the heat of the sun. Prefer- On the accompanying drawings, Figure 1v ably this composition'has incorporated in it some suitable inert pigment, e. g. ground hematite ore, which will impart a pleasing color thereto and increase its fire-resisting qualities.' The material is made in long sheets and is cut into sizes and shapes proper for the tile blanks.

We have illustrated various tiles in various shapes for producing di'erent ornamental eft'ects when laid upon the roof. 1n the formation of these several tiles to secure the results to be accomplished, it is necessary to bend, fold and otherwise shape them. This cannot be done conveniently during the operation of laying the tiles, for the reason that waterproof and weatherproof material of the class described cannot be bent ordinarily Without cracking and breaking the coatings ,or facings, especially when the weather is moderately cool. When the coatings have been treated to render them soft and plastic, the material may be folded or bent at a sharp angle to stretch and elongate the coating at the bend or fold, and, if then caused to set or harden in the stretched condition, the coatings will not break when the folded portion is bent back and forth about the hinge thus formed.

In Fig. 5, we have shown a tile blank formed of the described material. Its main body portion is substantially rectangular in outline', as at 20, and it has at its lower portion a tab 21 which is folded under on the line 22 to form a thickedge portion.l By suitable apparatus, the blank is bent on the lines 23, 24 and 25 to form an upstanding. rib 26 and to provide two curved side portions or wings-27, 28. That at 27 is shown as considerably wider than that at 2 8 but that is not a materialvfeature. The folded-under lower marginal portion 21 forms with the side portion 27 of the body a pocket or recess to receive the wing or side portion 28 of the next adjacent tile, 'so as to interlock the twotiles together and producei a practically continuous exposed the supporting structure 29' are placed parallel supporting bars 30, 30, suitably spaced apart. Then a horizontal row of tiles 1s laid upon' the roofso that the lower edges of the ribs rest upon the-structure mldway between the supports and the curved portions 27 bridge the supports. Each tile is interlocked with the next adjacent tile, by slippingthe portion 28 inthe recess formed by the folded-under portion 21 thereof, as shown in Fig. 4, so that said portion 28 is overlapped by the body portion 27 by s ald adjacent tile. The underlapping portlon 28 serves `to strengthen and support the arched rib formed by the portion 27.

The upper portions of the tiles are secured in place by nails or other fastenings,

v which may be located in the V-shaped recesses-formed by the angular ribs, or passed through the arched support or curved ribs into the bars 30. When the next row of tiles is laid, the lower portions of the latter cover and conceal the fastenings andthe holes made thereby. When the roof is complete, the folded edges of the tiles are practically continuous and are` so thick as to give a semblance of solidity and rigidity to the roof. The bars 30 are unnecessary to support or maintain the contour of the arching ribs, but are employed to prevent the ribs from being crushed by anyone walking upon the roof.` When laid,.the roof has alternating curved or arching ribs, and angular ribs, which extend `from the eaves to the ridge thereof.l

InJ Figs. 7 to 10'inclusive, the tiles are laid with twov angular ribs intervening between each pair of arching or curved ribs. In this case, the blank 40 is made wider, and its side portions are bent on the lines 41, 42, 43, 44 and 45, to provide two angular ribs 46, 47, one on'each side of the arched rib 48, and an upturned lateral marginal portion 49. The lowerY portion of the blank is folded under, except below the rib 46, so as to receive the rib 46. and portion 49 of the'next adjacent tile, in Figs. `7 and 8. This form of tile may be laid to provide two intervening angular `tion 52 which ribs or ridges as shown in Fig. 8, or to provide a single intervening rib as shown in Fig.. 9, this depending upon the extent to which the two tiles overlap laterally.

A`In Figs. 11, 12, 13,' 14 and 16, we have illustrated another embodiment ofthe invention linV which there are no intervenin angular ribs, but in which the tiles laterally vn'this case, each tile blank 50 which `is less in length than the width of the blank,- and is overlapped by the next adjacent tile,

which slips into and is interlocked in the recess formed by the tab 51 of said next adas shown clearly lower edge portion,

which provides a lateral porand the lower edge portion of jacent tile. The roofing thus formed is sinuous, the tiles being fastened by nails 53, 54 or other fasteners to the supports 30 and to the structure 29 between the supports. In this form of roofing, the laterally overlapping portions are concave.

In Figs. 16 and 17, the sinuous tiles are not interlocked, although each tile laterally overlaps an adjacent tile. With this form, the lower fold extends entirely across the lower portion of the body of the tile, but in such case the fastening 60 is driven through the turned-under fold or tab so as to be covered by the main body of the tile. In addition to these fasteners which are passed into the supports 30, there are others, 61, which are driven through a portion of each tile that is covered by an overlapping tile of the next row, and into the supporting structure 29 to cause the sinuous tiles to retain their contour when laid.

In both forms of roofing shown in Figs. 11 and 15, there are parallel convex ribs which extend toward the ridge, although these ribs are not so pronounced 'as in the form of tiles previously described. In all of the forms of tiles, there are the foldedunder lower edges, which overlap the tiles of the immediately adjacent lower rows, and the lateral overlap of each tile upon the next adjacent tile of the same horizontal row.

Having thus explained the nature of our said invention, and described a way of making and using the same, although without attempting to set forth all of the forms in which it may be made or all of the modes of its use, what we claim is:

1. A flexible non-metallic roofing tile consisting of a fibrous waterproof foundation coated with a weatherproof substance, said tile having a central arched or convex rib longitudinal thereof, a folded-under lower edge portion, and a side'portion projecting beyond the end of said folded portion to be within the folded-under lower edge portion of the next adjacent tile.

2. A roof of flexible non-metallic tiles coate with a weatherproof substance, said tiles being arranged in vertically overlapping transverse rows, each tile being conversely curved and having a fiexibly connected folded-under a lateral portion to overlap and interlock with said folded-under lower edge portion of the next adjacent tile 1n the same horizontal row, and fasteners passed through said folded-under portions ailid covered by the body portions of said 3: A flexible non-metallic roofing tile consistlng of a fibrous waterproof foundation c oated with a weatherproof substance, Said t1le having a flexibly connected folded-under lower edge portion anda side portion projecting laterally beyond the lower edge portion, said blank having a central arched portion, and angularly bent side portions to form ribs, and being adapted to be expanded and contracted laterally to vary the angularity of said ribs and the curvature of said,

central portion.

4. A roof comprising a supporting structure, a plurality7 of parallel bars thereon, and a plurality of flexible non-metallic tiles each consisting of a flexible waterproof foundation having a coating of weatherproof substance, said tiles being arranged in vertically overlapping horizontal rows, each tile bridging one of said supports, and laterally overlapping an adjacent tile, said tiles being folded under at their lower edge portions, and fasteners covered by the body portions of said tiles for securing them to said bars and to the supporting structures between saidbars t0 produce a sinuous surface.

l[n testimony whereof we have aflixed our signatures, in presence of two witnesses.
